CBS News reporter Armen Keteyian and a camera crew were inside the NFL control room at the Superdome at the precise moment the Super Bowl blackout occurred Sunday night. Watch "Going Dark: Lights Out in the NFL Control Room" as NFL and Superdome officials calmly but urgently assess the situation, which halted play for more than a half-hour at the start of the third quarter.

Keteyian was there to report a Super Bowl 2013 behind-the-scenes feature for this week's "60 Minutes Sports" telecast, airing at 9 p.m. Wednesday on Showtime. He was in the process of interviewing NFL Senior Vice President of Events Frank Supovitz about the staging of Beyonce's halftime show when the Dome darkened.

SMG Senior Vice President Doug Thornton is seen giving Supovitz the bad news.

"We lost the A-feed," he says.

"What does that mean?" Supovitz responds.

"That means that we have to do the bus tie," Thornton says.

"What does that mean?" Supovitz asks again.

"That means about a 20-minute delay," Thornton says.

TV columnist Dave Walker interviewed Keteyian about the segment; see his interview, and read more details about Wednesday's telecast, here.
